1I.M. Setchenov First Moscow State Medical University, Moscow, Russia.
New pharmaceutical formulations are being developed to improve the treatment of oral mucosal lesions. These advanced drug delivery systems offer better adhesion and prolonged therapeutic effects for dental patients.
Area of Science:
- Dentistry
- Pharmaceutical Sciences
- Biomaterials
Background:
- Pathological lesions of the oral mucosa are common in dental practice, stemming from diverse causes like infections and physical agents.
- Traditional topical treatments (ointments, gels) exhibit limited efficacy due to poor drug concentration maintenance, short contact times, and patient discomfort.
- These limitations necessitate the development of advanced pharmaceutical forms for improved oral lesion management.
Purpose of the Study:
- To address the limitations of conventional topical therapies for oral mucosal lesions.
- To explore the development of novel pharmaceutical forms with enhanced adhesion and prolonged drug release.
- To improve the therapeutic outcomes and patient experience in managing oral mucosal pathologies.
Main Methods:
- Development of novel pharmaceutical formulations designed for prolonged activity and improved mucosal adhesion.
- Evaluation of drug concentration maintenance and contact duration at the lesion site.
- Assessment of protective properties against infection and external irritants.
- Clinical evaluation of pain reduction during mastication and mimicry.
Main Results:
- New barrier drugs and prolonged-release formulations demonstrate improved adhesion to oral mucosa.
- These advanced forms maintain therapeutic drug concentrations for extended periods.
- Enhanced protection against oral infections and external influences, with reduced pain during oral functions.
Conclusions:
- Advanced pharmaceutical forms, including barrier and prolonged-release drugs, offer significant advantages over traditional topical treatments for oral mucosal lesions.
- These novel formulations improve therapeutic efficacy, patient comfort, and treatment duration.
- Ongoing research and development continue to refine these pharmaceutical strategies for broader clinical application.
